Probably, but even if you've never used a calculator, *learning* to
use a calculator is a lot easier than learning to use a computer. The
reason is simple: affordabilities. A basic calculator (I'm not
talking about those TI models) has a small number of buttons, each
with a single function clearly labeled. "+" means plus, and so on.
Compare that to a computer: the keyboard has over 100 keys, there's a
mouse, there are buttons on the screen, etc., etc. Between all that,
** for power seems a minor issue (and easily solved, as Laura showed).
